LITTLE ROCK — TLC reality show "19 Kids and Counting" may soon need a new name.

Arkansas couple Jim Bob and Michelle Duggar appeared with their burgeoning clan on NBC's "Today" show Tuesday and announced they are expecting their 20th child in April.

Forty-five-year-old Michelle Duggar said she's in good physical shape and that she's not worried, despite complications during her last pregnancy that led to the premature birth of their youngest child two years ago. She says she's made it through her first trimester safely.

The couple has said they don't use birth control. Michelle Duggar said she didn't necessarily expect to get pregnant again and that she and her husband are excited to welcome the new addition to the family.
